i have a UC_Categories.ascx ( UC_1 ) which constraints categoryname . UC_Products.ascx ( UC_2 ) will show products by categoryname. Both of them are in a Page called BookShop.aspx ( Page )

In the Page, when user click a UC_1 (step 1 ) , it will render a UC_2 by categoryname (step2 ). I process step 1 by sending a request with param that is categoryname to Page. Step2 create a new UC_2 ,set Properties value that is categoryname , and execute FillProductByCategoryName method. then add UC_2 to a PlaceHolder in the Page. but i don't show UC_2 .

I need a help or suggest from everyone.

Thank you for reading my question! ps : my english isn't very well.

in the codebehind of the UC2 :
Code:
public void FillProduct()
{

ProductsMN productsMN = new ProductsMN();
if (dlBook == null)
{
dlBook = new DataList();
dlBook.DataSource = productsMN.GetByCategoryName(CategoryName);
dlBook.DataBind();
}
else
{
dlBook.DataSource = productsMN.GetByCategoryName(CategoryName);
dlBook.DataBind();
}
}

public string CategoryName { get; set; }
in the codebehind of the page

protected void Page_Load(object sender, EventArgs e)
{

if (!IsPostBack)
{
}
string categoryName = Request.QueryString["categoryName"] as string;
if (!string.IsNullOrWhiteSpace(categoryName))
{
BookContent.Controls.Clear(); // BookContent : Placeholder
Control c = Page.LoadControl("~/UC/UC_Books.ascx") as UC.UC_Books;
UC.UC_Books ucBook = new UC.UC_Books();
ucBook.CategoryName = categoryName;
ucBook.FillProduct(); //line 10
BookContent.Controls.Add(ucBook); //line 11
}

}
at the PageLoad of the Page, useBook contains data. but in the Page (view ), i don't see data. i think //line11 isn't execute or not true .

Please use appropriate formatting tags when posting code for the sake of readability:

public void FillProduct()
    {
 
        ProductsMN productsMN = new ProductsMN();
        if (dlBook == null)
        {
            dlBook = new DataList();
            dlBook.DataSource = productsMN.GetByCategoryName(CategoryName);
            dlBook.DataBind();
        }
        else
        {
            dlBook.DataSource = productsMN.GetByCategoryName(CategoryName);
            dlBook.DataBind();
        }
    }
 
    public string CategoryName { get; set; }

protected void Page_Load(object sender, EventArgs e)
    {
 
        if (!IsPostBack)
        {
        }
        string categoryName = Request.QueryString["categoryName"] as string;
        if (!string.IsNullOrWhiteSpace(categoryName))
        {
            BookContent.Controls.Clear(); // BookContent : Placeholder
            Control c = Page.LoadControl("~/UC/UC_Books.ascx") as UC.UC_Books;
            UC.UC_Books ucBook = new UC.UC_Books();
            ucBook.CategoryName = categoryName;
            ucBook.FillProduct(); //line 10
            BookContent.Controls.Add(ucBook); //line 11
        }
 
    }
